ABSTRACT
Rose Bengal is used as a photo sensitizer in photo galvanic cell for solar energy conversion and TEAis used as an electron donor in this study. The effects of various parameters like pH, light intensity, diffusion length, reductant concentration and dye concentration on the electrical output of the cell is studied. The photo potential and photocurrent generated by this cell are 840 mV and 145μA, respectively. The current voltage (i–V) characteristic of the cell is also studied and a mechanism for the generation of photocurrent is proposed.
